Scooby and Shaggy win a dinner with Vincent Van Ghoul, but the meal is interrupted by monsters from van Ghoul’s movies. The three run, but a fourth monster, Nightfright, emerges, prompting van Ghoul to reveal that Shaggy and Scooby are on a reality show where unsuspecting fans dine with van Ghoul only to get attacked by monsters from his movies. Nightfright, however, is not one of those monsters and is not part of the show. Fred, Daphne, and Velma arrive after being called for help. A script featuring Nightfright is found, and the monster is revealed to be Arcus Fentonpoof, who only wanted his script adapted by proving Nightfright is scary.
